- Abstract:
-
We analysis the noise level of stations by using the statistical characteristics of background noise power spectral densities when the effective frequency is in the range of 1~10Hz at Binchuan region.The results show that the quality of records can be improved greatly with better observation condition and environment,the superposition of air-gun signals with high signal-to-noise ratio can be reduced,and the farther propagation distance also can be achieved with the same superposition by building and maintaining the stations with high quality.
